Soil performance is affected by various factors with which it interacts, for example, freezing and thawing cycles, which cause internal volumetric changes. For that reason, in this thesis, the effects of temperature changes in a gravelly clayey soil are studied, using temperature cycles ranging from -5°C to 17°C for 10 days. Likewise, the use of lime and polypropylene fiber are proposed as a proposal to mitigate the reduction of resistance. For this, 4 dosages are proposed, which includes 3 samples mixed with the proposed materials and a sample in its natural state, all with their maximum dry density. Additionally, two groups of samples are formed with these dosages, where the first is subjected to temperature cycles to then carry out the compression test at room temperature, and the other group is tested moments after being molded, to finally compare them. In this way, an optimal ratio is found based on the variation in compressive strength between the samples that were subjected to temperature cycles and those that were not. As a result, it is obtained that the use of 3% lime and 0.5% polypropylene fiber allowed the freezing cycles to cause a lesser effect on the soil, since the resistance was reduced by only 6.76%, compared to the patron sample (without materials) which was reduced by 12.28%.
